Different engagement types need different brief emphasis.
Project work (one-time deliverable)
Emphasize: specific deliverables, success criteria, timeline, handoff expectations. Vendors quoting projects need to scope the work precisely; specifics help them quote accurately.
Example areas: theme customization, flow build, audit, migration, custom feature build, App Store app build.
Brief weight: heavy on element 5 (desired outcome with success criteria) and element 6 (constraints, especially timeline).
Retainer engagement (ongoing relationship)
Emphasize: cadence of work, types of work expected each month, success metrics over time, what you need from the vendor on an ongoing basis. Retainers benefit from clear expectations about ongoing work rather than specific deliverables.
Example areas: ongoing development, email marketing operations, SEO programs, maintenance retainers, CRO programs.
Brief weight: heavy on element 5 (desired ongoing outcomes) and element 7 (team and decision process — how you will work together over time).
Audit or diagnostic (one-time advisory)
Emphasize: what you want diagnosed, what decisions the audit will inform, what scope of recommendations you want. Audits produce documents, not implementations — the brief should clarify what document you want.
Example areas: speed audit, conversion audit, SEO audit, app stack audit, security audit, technical due diligence.
Brief weight: heavy on element 4 (suspected root cause) and element 5 (desired outcome: what decisions will the audit inform).
Strategic consulting (advisory)
Emphasize: the decisions you are trying to make, the alternatives you are considering, what success looks like for the consulting engagement. Strategic consulting is about decisions, not deliverables.
Example areas: fractional CMO/CTO, vendor evaluation, technology strategy, channel strategy, migration evaluation, build vs buy decisions.
Brief weight: heavy on element 2 (current situation) and element 7 (decision process).
Custom development (build something new)
Emphasize: the business problem (not just the technical solution), specifications you have already considered, integration points, constraints. Custom development briefs that name a solution without describing the problem produce vendors locked into the named solution rather than considering alternatives.
Example areas: custom apps, custom Liquid features, custom integrations, Plus Functions, Checkout Extensibility.
Brief weight: heavy on element 2 (specific symptom), element 4 (suspected root cause), element 6 (constraints including technical constraints).
Migration
Emphasize: source platform details, customization on source, integrations, subscription customers if any, B2B if any, SEO situation, timeline constraints. Migration scope depends heavily on source platform context.
Brief weight: heavy on element 1 (store context, including source platform), element 2 (current state), and element 6 (constraints, especially timeline and what cannot break).
